Public bug reported: This config worked on 13.04
a52.conf: pcm.a52 { @args [CARD] @args.CARD { type string } type rate slave { pcm { type a52 bitrate 448 channels 6 card $CARD } # rate 48000 #required somehow, otherwise nothing happens in PulseAudio } } commenting out rate 48000 allows it to work, but stereo only; no surround.
